Why is DEX not being made wireless?

Having to plug in a cable is better than the old docking station, but still not as good as wireless. I can't see any reason why this is not possible with a chromecast/mirrorcast adaptor. If the only purpose of the station/Adaptor is to transmit the video/audio, then the station/adaptor is unnecessary.

This would be amazing. Dex has been such a blessing for me, I would love to have the ability to connect it to something like the HP Lapdock. I am glad Samsung is moving forward with this. I honestly have been thinking about switching to Pixel for my next phone due to stock Android, but seeing that you guys are actually pursuing this is making me reconsider. I was able to successfully connect a Galaxy s8 to the Lapdock though smart view, and would love to see Dex enabled rather than the minimal mirror option.
